Description

Stick handle

Technical Field

The invention relates to a pole grip, in particular for a cross-country pole, a trekking pole, a skiing pole or a nordic walking pole, having a fastening mechanism for a hand strap, which fastening mechanism allows the hand strap to be fastened in variable lengths, wherein the fastening mechanism is arranged in a recess in the region of the head of the pole grip.

Background

The pole grip is traditionally fixed in the user's hand in the following manner: a hand strap is fixed in the region of the head of the pole grip, into which the user inserts and then grips the pole grip through the hand strap. For different hand sizes, but also for different use cases, it is advantageous in such a hand strap to be able to variably adjust the length of the hand strap without having to use tools for this purpose. Accordingly, there are a number of technical possibilities for the variable fixing of the hand grip on the pole grip.

Such a fixing device should be as simple as possible in order to be inexpensive to produce and non-interfering in use, but at the same time should ensure that: in particular, an extension of the hand strap is only possible if the respective fastening mechanism is actively released for adjustment.

Disclosure of Invention

Accordingly, it is an object of the present invention to provide an improved pole grip, in particular for off-road walking poles, trekking poles, skiing poles or nordic walking poles, which has a fixing mechanism for a hand strap, which allows a variable length of the hand strap to be fixed. The fastening means are arranged in a recess in the head region of the pole grip. The pole grip proposed according to the invention is distinguished in particular in that the fastening means comprise a clamping element which is mounted so as to be rotatable about a rotational axis arranged transversely to the pole axis or pole grip axis and is arranged in a recess, wherein the recess is designed as a passage opening which is oriented at an acute angle to the pole axis, the lower opening of which opens out into or above the grip region of the rear portion facing the palm of the hand and the upper opening of which opens up onto the upper side of the pole grip.

Preferably, the clamping element has a lever region, which is arranged substantially in the passage opening and through which the rotational axis passes, and a head region, which projects above from the recess of the shank, preferably having a strap opening and a pressure surface for fixing the position of the hand in a clamping or fixing position, in which the strap length cannot be adjusted, and optionally also for displacing into a free position, in which the strap is not clamped and the length can be adjusted.

The strap is guided through the passage opening, through the lever region and, if present, through the strap opening of the clamping element or through the head region and projects above the passage opening or the strap opening with the free end.

The clamping element can thus be fixed in a clamping position in which the strap is clamped in a force-and/or form-fitting manner (preferably directly one on top of the other) between the lever region and the wall of the passage opening or a fixing element (preferably fixed in or on the passage opening) in that: the locking projection of the clamping element is releasably locked behind the projection of the button head or behind the locking projection of the fixing element. The locking or clamping can be released by the clamping element tilting about the axis of rotation, preferably towards the forward travel direction, by releasing the locking projection.

A first preferred embodiment is characterized in that the clamping element has in its head region an arcuate region which faces the hand strap and is directed rearward in the direction of travel and a pressure surface which is arranged forward in the direction of travel, wherein preferably the arcuate region surrounds and forms the strap opening and, at a region of the arcuate region which is located forward in the direction of travel, is preferably designed as a downwardly directed projection which, in the clamping position, is releasably locked behind the projection of the tang head or behind the locking projection of the securing element.

The arcuate region can have arcuate recesses on both sides toward the shank portion, which makes it possible to adjust the optimum bending flexibility of the locking projection.

The recess can have a receiving recess, preferably a T-shaped recess with a region facing the opening of the clamping element and two lateral widenings, in the region facing rearward in the direction of travel and in the wall section of the inner wall, in which receiving recess the fastening element is fixed.

The fixing element can also have a retaining region which is inserted into the recess and a locking projection which projects over the shank for the locking projection.

A further preferred embodiment is characterized in that the region of the lever region and/or the region of the inner wall of the recess which faces rearward in the direction of travel and the wall section, and/or the region of the holding region of the fastening element which is exposed toward the clamping element, have means for fastening the strap, preferably in the form of teeth, pins, ribs and/or a friction-reducing coating.

The pole grip can also comprise a wedge which, in the latched position, can be inserted between the lever region and the wall of the through-opening with a friction fit and/or a force fit and/or a form fit, so that the clamping element can no longer be pivoted into the unlatched position. Preferably, the free end of the strap (15) is fixed to the wedge (43).

The fastening element can be arranged in the receiving recess, wherein its front side can form a mating pressure surface, towards which the holding region directly clamps the two strips.

The clamping element can, but need not, be acted upon by a restoring force, preferably clamped against the inner wall, by means of a resilient restoring element, in particular a spring, preferably a leaf spring or a helical spring, or a resilient region of the lever region. For example, it is possible that the lever region can project slightly downward beyond the pivot axis and that its projecting region is designed such that it is easily clamped in the clamping position against a boundary wall in front of the through-opening due to material deformation. This results in ensuring, when released from the clamping position: the clamping element is pivoted into the open position as automatically as possible. It is of course also possible for the teeth provided on the clamping element or on the fastening element to engage into the material of the two strips and then it is desirable to assist the movement of the clamping element into the open position. Of course, it is also possible to use a helical or leaf spring which urges the clamping element into the open position.

According to a further preferred embodiment, the rotational axis of the clamping element can pass through the lever region transversely to the direction of travel in the region of its lower end, wherein the lever region preferably projects into the through-opening from above by more than 30%, preferably more than 40%, of the length of the through-opening measured at its front inner wall.

The head region can have a forwardly directed, downwardly inclined ramp surface, in which an upper opening can be provided, and the clamping element can approach or project from the opening at least partially by means of the pressure surface and the curved region via the upper opening in the region of the ramp surface. In the accessible region or the region extending beyond the upper opening (10) is designed as a pressure surface for tilting operations, in particular into a clamping position.

The release element preferably has a widening which is directed forwards and downwards with respect to the direction of use of the pole grip and which at least partially, preferably substantially completely, covers the gap between the release element and the wall bounding the upper opening of the recess in order to prevent the entry of dirt and/or snow and/or ice.

A further preferred embodiment is characterized in that the grip has a recess on the underside for receiving the pole tube, which may be multi-part. In the recess, a retaining pin can preferably be provided which engages into an inner space of the inserted pole tube, said retaining pin preferably being formed in one piece with the grip body.

The clamping element and/or the fastening element and/or the shank portion are made of a thermoplastic, preferably polyamide, polyester, polyolefin, PET or mixtures thereof, in a non-reinforced or glass-fiber-reinforced form. In this case, in particular in the area of the arc, a design made of a material which at the same time allows simple but nevertheless latches into the fixed position, but which on the other hand is not too rigid to be released again, is advantageous.

The pressure region of the clamping element can preferably be delimited to the rear in the direction of travel by a preferably transversely extending projection in order to simplify handling.

The lever region is preferably substantially aligned with the pressure region arranged above, and the curved region is also preferably molded back onto the lever region in the direction of travel.

The hand strap can be a single strap, a strap securable to the hand with three separate openings for the thumb, fingers/back of the hand and wrist, or a glove with straps secured thereon.

The hand strap can be a single strap (a strap, typically made of a woven fabric, in particular a dimensionally stable plastic fabric, typically having a thickness in the range of 0.3mm to 2mm, and/or in general having a width in the range of 3mm to 20mm, preferably having a width in the range of 4mm to 10mm, wherein the width is suitable for the region that can be placed in the fixing region, the region located in the region of the hand can also be configured to be wider, and in particular having a region made of, for example, neoprene, for example soft sewn). Alternatively, it can be a strap that can be fixed on the hand, with three separate openings for the thumb, fingers/back of the hand and wrist. Typically, such a strap is configured to be adjustable around the eyelet by means of velcro. Alternatively, it can also be a glove with a strap attached to it.

Such pole grips typically have a sleeve made of hard plastic with a soft coating in the grip region, and such elements can be produced by two-component injection molding. The release element is preferably likewise made of hard plastic, wherein the above-mentioned teeth can be made of the same material (in one piece), but can also be formed, for example, by a metal filling or the like. Typically, the rotary shaft for the clamping element is made of metal or plastic or a combination thereof and, after insertion of the clamping element (and possibly of the fixing element), can be pushed laterally into the recess through two correspondingly opposite openings in the material of the crown, wherein the openings in the crown and the shaft opening in the clamping element are passed through.

The invention further relates to an all-terrain pole, a trekking pole, a skiing pole or a nordic walking pole having a pole grip according to the above.

Other embodiments are given below.

Detailed Description

Fig. 1 shows a pole grip 1 with a device according to the invention for variably determining the length of a hand strap 23. The pole grip 1 has a grip body, on the underside of which a recess 2 for a pole shaft is formed. In the travel direction 35 of the shank portion with the front grip region 3 and the rear grip region 4, a specific grip region made of cork is constructed for a better feel. The actual shank body is formed by a plastic sleeve 5 made of hard plastic. The grip region 4 located at the rear in the direction of travel is formed with an opening 9 above the grip region but below the head region of the grip, through which opening the band 16 of the hand strap 23 passes out of the grip head, followed by a hand strap with three openings, one for the thumb, one for the remaining fingers and one for the wrist. However, a single strap can also be so secured.

The two webs 16 pass through the button head, more precisely from below through the recess 8, which is open upwards, i.e. it has an upper opening 10 in addition to the lower opening 9. The corresponding recess 8 accordingly receives the strip 16 from below and leaves the lug head with its free end 15 or 15' from above. However, the strip can also be inserted again at least partially into the crown from above or into the clamping device described below, so as not to be disturbed there above the crown in use.

The recess 8, which is elongate and is arranged at an acute angle to the pole axis and is in the form of a through-opening, is provided as a clamping element 11. The clamping element 11 has a shaft bore arranged transversely to the pole axis, through which the rotary shaft 7 is mounted in two shaft bores 6 arranged laterally opposite one another in the sleeve. The clamping element 11 is correspondingly rotatably or pivotably supported via the shaft 7 within a small angular range, typically not more than 10 to 15 degrees.

The actual clamping device comprises a clamping element 11 which is arranged in the recess 8 and is rotatably or tiltably supported about an axle 7 supported in two opposite axle bores 6. For this purpose, the clamping element 11 has a lever region 14, which has a through-opening in its lower region, through which the rotary shaft 7 passes. The lever region 14 is arranged in the crown.

The clamping element 11 protrudes from the crown in an upper region. The upper region comprises the pressure region 12 and the region pointing rearwards in the direction of travel 35, which comprises the arc-shaped region 20. The curved region 20 surrounds a belt opening 22 through which the two belt strips 15 pass again upwards after they have passed through the recess 8 from below. A locking projection 24 is provided or molded downward on a region of the arc-shaped region located rearward in the direction of travel. Thereby, a connecting rod 36 is also produced for releasing the mechanism, i.e. in order to move into the position according to fig. 1 b.

On the other side, the fixing element 17 also enters into the crown. The fixing element protrudes upwards from the upper edge of the tang head and there is provided a locking projection 31 behind which the locking projection 24 engages in the fixing position.

When the fixing element 17 is in the clamping position and the locking projection 24 engages behind the locking projection 31, the two straps 15 are clamped between the lever region 14 of the clamping device 11 and a holding region of the fixing element which is arranged downwards in the recess 8, so that the length of the hand strap 23 is fixed in this position.

The release position of the mechanism is shown in fig. 1 b. Here, the clamping element 11 is tilted slightly forward in the direction of travel, i.e. the locking projection 24 has released the locking projection 31 and pivoted forward. Accordingly, the lever region 14 is also removed from the inner wall arranged behind in the direction of travel or the fastening element 17 arranged there, and the two webs 16/15 are now no longer fastened in the crown and can be adjusted in terms of their length, i.e. moved in the crown.

The clamping element 11 can be pushed back into the fastening position again by the pressure surface 12. In order to bring the clamping mechanism from the closed position according to fig. 1a into the release position according to fig. 1b, the clamping element 11 can be pushed or tilted forward by pressing in the region of the locking projection 24 with the thumb, if necessary even with the thumb belonging to the hand located in the bracelet.

Shown in FIG. 1 c: how the gripping element 11 can be pushed back again with the thumb by abutting against the pressure surface 12, assisted by the projection 33, enables the locking projection 24 to snap behind the locking projection 31 and thus enables the two webs 16/15 to be fixed in their position again.

Fig. 2 shows a different view, wherein the band and the tape are removed, so that the recess 8 and the components arranged there can be better viewed. Fig. 2a shows a view of the recess 8 from above. In this case, it is possible to identify: how the arc-shaped region 20 surrounds the band opening 22 and how the pin 21 is arranged, in particular, on the side of the lever region 14 of the clamping element 11 facing the band for clamping the band, so that the two bands are held well.

It is to be noted in this connection that the two bands are stacked one above the other in the clamped position. It is also advantageous if such a pin 21 is provided not only on the lever region 14, but also on the opposite side of the recess 8. In this exemplary embodiment, the opposing faces are formed by retaining regions 34 of the fastening element in recesses in the crown, but it is also possible for the recesses to be formed simply directly on the inner side. The holding region 34 of the fastening element 17 also has a pin 19, i.e. each of two overlapping strips is likewise held or fastened from both sides by a pin.

In fig. 2c, a side view is shown: how the fixing element is pushed into the corresponding receiving recess 18 in the crown. The receiving recess has two lateral widenings 30, into which the corresponding widenings 30 of the fastening element 17 engage. Accordingly, the fixing element 17 has a retaining region 34 which is pushed into the crown but is exposed towards the band on the inside of the recess 8 and has the pin 19 there for clamping. On the other side, the fixing element 17 has a region 31 projecting upwards from the lug head, which region provides a locking projection 31. It is thus possible, for example, to insert such a device into a standard crown which itself has other fixing means.

The fixed position of such a pole is clearly shown in fig. 3. It can be recognized here how the free end of the strip passes through the opening 22 upwards. It is also possible to identify: how large the band opening 22 is enough for the two free ends 15, if desired, to be pushed again at least partially into the band opening 22 by means of its tip, so that it does not interfere in use.

One advantage of such clamping is a degree of self-clamping under increased tension.

A problem with this mechanism may be the fact that: in the clamped state, the region between the inner wall 26 of the front part and the clamping element 11 must have a certain gap size in order to be able to achieve tilting. Dirt or ice or also snow can penetrate through this gap into the interior of the recess and block or even damage the mechanism for a long time. In order to prevent this problem, the clamping element 11 has a lower projection 13 on its front side, which engages over the gap even in the clamped state, so that only a very narrow, constant gap remains. Thus, a labyrinth seal is provided to some extent, and if the gap is chosen substantially tangentially to the direction of rotation about the shaft 7, the gap size can be chosen to be very small without thereby adversely affecting the movability of the clamping element 11. Such sealing measures can also be implemented in other ways, for example by flexible sealing lips or by groove/tongue solutions, which can furthermore be implemented not only in the lower region but also laterally in the gap between the release element 11 and the side wall of the recess 8.

In fig. 4 to 6, the pole grip is again visualized in a more detailed technical view. In particular, further details can be identified in the sectional views.

In fig. 4, the open position is shown, in which the clamping element 11 is tilted forward in the direction of travel 35 and accordingly no clamping strap is present (the strap is not shown in fig. 4 and 5 for the sake of visualization). In particular, it can be seen from fig. 4b how the recess has a lower opening 9 and an upper opening 10 in the head region of the pole grip, through which the strip enters the recess 8, and through which upper opening 10 the strip projects upwards from the pole grip. The opening 8 has a front inner wall 26 and a rear inner wall 27. The clamping element 11 has the mentioned lever region 14 which engages from above into the recess 8 and is traversed at its lower end by the rotational axis 7 arranged transversely to the direction of travel.

Below the axis of rotation 7 there is a widening, which is designated by reference numeral 37 in fig. 4 to 6.

As can be seen in particular in fig. 5b, in the clamped position, the contact region 37 abuts against the front inner wall 26, which causes: if the clamping element 11 is released from the clamping position shown in fig. 5, a restoring moment is generated into the open position of the clamping element 11, by the pressure surface 36 being pushed forward in the direction of travel and possibly slightly upward.

Likewise, it can also be recognized from fig. 4c), in particular, that the arc-shaped region forming the band opening 22 is naturally curved to some extent on the one hand to form the band opening 22, but also has an arc-shaped recess 42. The curved recess 42 results in that the rear curved region 20 and the locking projection 24 can be optimally configured with respect to the bending behavior, so that the locking projection 24 can be locked as optimally as possible behind the locking projection 31 of the fastening element 17.

Furthermore, fig. 4 and 5 clearly show the holding region 34 of the fastening element 17, which has the toothing 19 provided there. The opposite rear side of the lever region 14 is likewise provided with a toothing 21, so that two strips lying one above the other are also secured virtually in the direction of stretching without loosening. The toothing on both sides is important because the two strips overlap one another in this clamping region, thus ensuring that: in fact, the two strips are also held in the clamped position by this additional form fit, not only by the friction fit.

According to fig. 6 and in this case in particular according to fig. 6b), it can be further recognized how the two straps 15, 15' are fixed in the clamping position shown in fig. 6, in particular flat, one above the other and from both sides by means of teeth. That is to say, the toothing 17 on the fastening element 17 enters the strap 15' arranged on the rear side from the side located behind in the direction of travel, and the toothing 21 on the clamping element or on its lever region 14 enters the strap 15 arranged on the front side.

After being fixed in the clamped position, the free ends of the straps 15, 15' can optionally also be pushed back into the remaining through-openings 22 again, so that the projecting region is as small as possible. This is possible by the wide design of the through-opening 22 in the upper region.

Another embodiment is shown in fig. 7. In addition to the locking, the clamping mechanism can also be completely fixed by means of the wedge 43. The wedge 43 serves on the one hand to prevent the lever region 14 of the clamping element 11 from pivoting in the loosening direction. On the other hand, a free end of the strap projecting upward from the clamping device is fixed to the wedge 43.

In this further embodiment, the front actuating region 40 is not formed to some extent as part of the clamping element 11, on the basis of the clamping mechanism as shown in the preceding figures. The front actuating region is cut off to some extent and provided with a holding region 45 facing downwards. The retaining region 45 is wedge-shaped and, when the clamping element is in the securing position, engages in the gap formed between the lever region 14 of the clamping element 11 and the front inner wall 26 of the recess 8 in the region of the pole grip.

In order to retain the retaining region 45 of the wedge 43 in this pole grip region, likewise not only via a friction fit, the retaining region 45 has a locking projection 48' on the side facing the lever region 14, and the lever region 14 has a locking groove 48 on the corresponding mating surface. Obviously, the grooves and projections can also be arranged interchangeably, and there can be a plurality of such elements.

In the upper region, the wedge has a step 46 in the region facing the clamping element 11. In this step, a blind hole 47 is provided, so that the free end of the strap can be introduced into the step and fixed or firmly bonded therein by means of a fixing screw, a fixing rivet or a pin 50 or a similar fixing element.

The wedge 43 also has a pressing surface 44 on its upper side, which serves to press the wedge 43 into the corresponding opening. The pressing surface 44 transitions as smoothly as possible into the pressure surface 12 of the clamping element 11.

If this mechanism is to be released from the locked state shown in fig. 7c), the curved guide strip 15 can be pulled, said strip 15 extending from above from the pole grip. Since the free end of the strap 15 is fixed in the step 46 of the wedge 43 via the pin 50, the wedge 43 can be pulled out of the pole grip, thereby releasing the groove/tongue fastener 47/48. The free end of the strap, to which the wedge 43 is fixed, is now free to hang.

The clamping element 11 is now released in terms of its mobility in the opposite direction to the fixing element 17 and can be released, for example, by pressing on the pressure surface 36, i.e. the locking projection 24 is lifted over the locking projection 31 and the clamping element 11 is pivoted. The gap between the toothed regions is then released and the belt can be adjusted in its length.

If the mechanism should be clamped again in order to determine a specific belt length, the clamping element is pivoted again by pressing on the pressure surface 12 and the locking projection 24 is locked via the locking projection 31. Subsequently, the wedge 43 is pushed into and locked in the now open gap between the lever region 14 and the inner wall 26 of the front part. The strap is thus completely fixed and the free strap ends become neat.

Fig. 7 also shows a specific design of the toothing on the fastening element 17 and the lever region 14 of the clamping element 11. There are three rows of teeth evenly distributed in height, said teeth also being slightly inclined with respect to the stretching direction.
